Ultrasonic thickness indicators of the TAU class

Record Control Number : 28138
Quality Validation Date : 2002-07-19
Update Date : 2002-07-25
Abstract : The ultrasonic thickness indicators (UTI)  are intended to measure 
		thickness of an article related to the time of ultrasonic wave 
		propagation. All devices of the TAU series allow to meter articles 
		that are subject to corrosion attacks. The transducer is kept upon 
		the surface at the expense of its contact with the penetrated.
		
		- The ultrasonic thickness indicators have a high-level 
		responsivity and stability to clutters (Patent No 2158901) , which 
		simplifies the measuring process considerably and improves 
		reliability of outcomes.
		- The instruments of this class are simple in use, have excellent 
		metrological performance, which allows testing the state of 
		machinery including use of untrained staff.
		- This thickness indicator is the cheapest in the Russian market, 
		which allows having a major store of devices with the small cost.
		- They require minimum operation expenditures, which include buying 
		batteries (all devices work with interior batteries)  and 
		transducers. Our transducers, with construction being protected by 
		the Patent, are dismountable and can be reconstructed multiple 
		without substitution.
		- The thickness indicators operate within a broad temperature range 
		from -40 up to +50°C, without drop of fidelity. That allows 
		utilising these devices in any climatic environment.
		- They have friendly shape and sizes.
		
		There is a sensor of high luminosity and special light screen, 
		which allows working with thickness indicators of the TAU class 
		with any interior lighting.
		
		The outside calliper is driven only by three push buttons, however 
		they have more broad functional capacities as contrasted to by 
		analogs, namely: auto calibration of hold time of ultrasonic four 
		alternatives of calibration according to a speed of sound, 
		portrayal of the last outcome of measuring, portrayal of relaxation 
		of the battery. Besides, the devices TAU 538 allow storing about 
		4000 inspection outcomes, bunched in arbitrary number of blocks. 
		They allow to read outcomes at recording and reading and a number 
		of the saved block, allow to execute rapid reading of outcomes 
		manually, and to transfer data to the computer, and report about of 
		the users' errors.
		
		The ultrasonic thickness indicators were tested and successfully 
		certificated as measuring facilities. Also there are favourable 
		opinions of experts who used to operate with our devices for the 
		purpose of ultrasonic inspection.
